Neuromuscular Electrical Stimulation in COPD/Community Acquired Pneumonia

Community-acquired Pneumonia Clinical Trial

Official title: Neuromuscular Electrical Stimulation (NMES) in Patients Hospitalized With Acute Exacerbation of COPD and/or Community Acquired Pneumonia

Status Recruiting

Clinical Trial Summary

In older adults hospitalized for acute medical conditions, immobility, clinical treatments, and the illness itself contribute to physical deconditioning and delirium, hospital-acquired impairments that increase risk for long-term physical and mental disability, other morbidities, and death. In patients with acute respiratory failure, hospital-acquired functional impairments persist long after hospitalization, due to limited use to rehabilitative interventions in the inpatient or post-acute settings. Exercise and early mobilization interventions are safe and improve physical and cognitive impairments, but there are critical barriers to their widespread implementation in acute care and home settings, including mobility limitations, reduced cardiopulmonary reserve, limited staff, and costs. Thus, there is an unmet need to develop interventions that can be utilized in both the inpatient and home environments to improve functional recovery in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and community-acquired pneumonia (CAP).

This study addresses this clinical need and these barriers and will provide important feasibility and acceptability data regarding the utility of neuromuscular electrical stimulation (NMES) administered to lower extremity musculature across inpatient and post-discharge settings to improve functional and cognitive recovery in older adults hospitalized for AECOPD/CAP.

Initial NMES sessions will begin during participants' stay at UVM Medical Center and will continue at home after hospital discharge. Study participants will be issued a portable NMES device to take home and instructed on its use. They will receive guidance and oversight on the use of the NMES device and will be asked to perform NMES treatments 6 days per week for 60 minutes per day for 6 weeks. Data will be collected via activity monitor, participant questionnaires and clinical assessments including strength testing and 6-minute-walk-test.

Clinical Trial Description

In older adults hospitalized for acute medical conditions, immobility, clinical treatments, and the illness itself contribute to physical deconditioning and delirium, hospital-acquired impairments that increase risk for long-term physical and mental disability, other morbidities, and death1-11. The syndrome of "long COVID" has drawn attention to the physical and psychological sequelae of hospitalization for acute respiratory illness (ARI), but this is not a new phenomenon. In patients with ARI, hospital-acquired functional impairments persist long after hospitalization, due to limited use to rehabilitative interventions in the inpatient or post-acute settings12-14. Exercise and early mobilization interventions are safe15 and improve physical and cognitive impairments16-19, but there are critical barriers to their widespread implementation in acute care and home settings, including mobility limitations, reduced cardiopulmonary reserve, limited staff, and costs. Thus, novel, interventions are needed that are portable, easy to use, and require minimal costs and equipment.

Community-acquired pneumonia (CAP) and acute exacerbation of chronic obstructive pulmonary disease (AECOPD) are leading causes of hospitalization in older adults20. These diagnoses often overlap21, cause substantial morbidity and mortality, and together account for >2.5 million hospitalizations and >$80 billion in costs annually22-28. Even before the COVID global pandemic, disability after hospitalization for AECOPD/CAP was on the rise29, due, in part, to an inability to remediate hospital-acquired impairments secondary to the lack of availability and low utilization of rehabilitation interventions13,30.

Physical rehabilitation improves mobility and attenuates hospital-acquired disability16-18, but these services are limited and their utilization in the hospital and after discharge is low. For instance, rehabilitation programs are absent or grossly underutilized for most general medical conditions, such as CAP. Even among patients with COPD, where rehabilitation has well-proven benefits and is supported by third party payers, uptake of pulmonary rehabilitation (PR) after hospitalization is very poor, with <3% participation within 1 year13. Low utilization of these services is due, in part, to barriers to delivering rehabilitation interventions in patient populations in the acute and post-discharge care settings, including inadequate staffing, costs, disease symptoms, reduced cardiopulmonary reserve, and lack of facility-based programs. Thus, there is an unmet need to develop interventions that can be utilized in both the inpatient and home environments to improve functional recovery in patients with AECOPD/CAP.

This study addresses this clinical need and these barriers and will provide important feasibility and acceptability data regarding the utility of neuromuscular electrical stimulation (NMES) administered to lower extremity musculature across inpatient and post-discharge settings to improve functional and cognitive recovery in older adults hospitalized for AECOPD/CAP. ;
